– Deoxyviolacein is a bacterial metabolite and byproduct in the biosynthesis of the bisindole alkaloid violacein, exhibiting anticancer, antibacterial, and antifungal properties. It inhibits hepatocellular carcinoma cell proliferation at concentrations of 0.1 to 1 μM. Deoxyviolacein (125 μg/ml) demonstrates antibacterial activity against Gram-positive bacteria, including S. aureus, B. subtilis, and B. megaterium, and showcases antifungal activity against R. solani at 2 mg/ml.
